A Nueces County Sheriff's Department investigator has been suspended after he allegedly fired a gun while arguing with his wife.

On July 4, Corpus Christi police responded to a shooting with injuries about 10:36 p.m. in the 6900 block of Saratoga Boulevard.

According to a Corpus Christi police arrest report, Ian Rosales, 31, called about the shooting.

"A male caller told the call taker that he shot his wife in the head and she is '32.' '32' is police code for dead," the report states.

When officers arrived, Rosales, an investigator who has been employed by the sheriff's department for more than 10 years, was seen walking out of the apartment with his hands up in the air.

"Officers approached Ian with weapons drawn and Ian went to his knees and put his hand behind his back already facing away from us," the report states.

Officers found Rosales' wife inside the apartment, unharmed.

The woman told police she and her husband began arguing after Rosales started "blowing his alcohol stenched breath in her face."

She then "nudged Ian with her hand in his face and told him to leave her alone," the report states.

The woman told police Rosales "got mad at her for hitting him and then became apologetic and walked off toward the bedroom saying he was going to kill himself."

The report states the woman heard one gun shot and then saw Rosales leave the room "with a blank stare on his face."

Rosales called the police in front of her and told them he shot his wife in the head, the report states.

The woman told police she "shoved him into the room afraid that he was going to try and harm her."

Rosales then walked outside when he heard the police sirens, the report states.

Officers found "a (bullet hole) in the ceiling and a hand gun laying in a hamper."

It was noted Rosales had no signs of injury or marks from the disturbance with his wife.

Rosales was arrested for discharging a firearm in certain municipalities which is a Class A misdemeanor.

It is unclear whether the gun fired was issued to Rosales by the department, said Daniel Perez, a Nueces County Sheriff's assistant chief. Perez declined to say if Rosales was suspended with or without pay.

Corpus Christi Police Public Information officers declined to release any details about the incident.

This isn't the first time Rosales has been arrested.

In December 2014, he was charged with driving while intoxicated. The charge was dismissed in October 2017 after Rosales completed a year of pretrial diversion.
